Investigation of the Ionospheric Short-Term Variability

Abstract

Both the total electron content of the ionosphere (TEC) and the critical frequency of the F2 layer (foF2) exhibit large day-to-day variations during quiet and active geomagnetic periods. It is of great interest to ascertain whether good correlation exists between TEC daily variability about the monthly mean and foF2 variations. With the availability of the global GPS constellation to provide instantaneous time-delay values such a correlation may enable the improvement of HF short-term predictions using passive monitoring of TEC. To determine the correlation, a pilot study was conducted using several months of TEC data taken in Haifa, Israel during 1980 as well as GPS time-delay measurements taken during the summer of 1992 in Jerusalem, Israel. The corresponding foF2 measurements were from Cape Zevgary, Cyprus.
